Network management system and data sharing method thereof

Abstract

A network management system includes a network management equipment (a video display equipment) having a server function and at least one terminal (a participant terminal) are network-connected. The network management equipment (the video display equipment) has a common key code used to authenticate a connection to a network. The network management system has a common key code device into which the common key code can be loaded, and then a user's terminal can be connected to the network by installing a common key code device (an Universal Serial Bus memory) into the user's terminal.

1 . A network management system, comprising: 
 a network management equipment having a server function; and at least one terminal are network-connected, wherein the network management equipment has a common key code to authenticate a connection to a network,    wherein the network management system has a common key code device into which the common key code can be loaded, and    wherein a user's terminal can be connected to the network by installing the common key code device into the user's terminal.    
   
   
       2 . A network management system according to  claim 1 , wherein the common key code device is an Universal Serial Bus memory.  
   
   
       3 . A network management system according to  claim 1 , wherein a term of validity of the common key code is previously set.  
   
   
       4 . A network management system, according to  claim 1 , wherein the user's terminal is connected to the network via at least one of a radio communication and a cable communication.  
   
   
       5 . A network management system according to  claim 1 , wherein the network management equipment is a video display equipment having a video displaying unit.  
   
   
       6 . A network management system for an electronic conference system, comprising: 
 a network management equipment having a server function; and at least one terminal are network-connected, wherein the network management equipment has a common key code to authenticate a connection to a network of the electronic conference system,    the network management system has a common key code device into which the common key code can be loaded, and    a user's terminal can be connected to the network of the electronic conference system as a participant terminal by installing the common key code device into the user's terminal.    
   
   
       7 . A network management system for an electronic conference system according to  claim 6 , wherein the common key code device is an Universal Serial Bus memory.  
   
   
       8 . A network management system for an electronic conference system according to  claim 6 , wherein a term of validity of the common key code is previously set.  
   
   
       9 . A network management system for an electronic conference system according to  claim 6 , wherein the user's terminal is connected to the network via a radio communication or a cable communication.  
   
   
       10 . A network management system for an electronic conference system according to  claim 6 , wherein the network management equipment is a video display equipment having a video displaying unit.  
   
   
       11 . A data sharing method of network-connecting a network management equipment having a server function and at least one terminal to share data via the network management equipment, comprising: 
 loading a common key code, which is used to authenticate a connection to a network, from the network management equipment to a common key code device;    rewriting a network setting of a user's terminal to a setting corresponding to the network, by reading the common key code from the common key code device installed into the user's terminal; and    connecting the user's terminal to the network based on the rewritten network setting of the user's terminal.    
   
   
       12 . A data sharing method in an electronic conference system that network-connects a network management equipment having a server function and at least one terminal to share data via the network management equipment, comprising: 
 loading a common key code, which is used to authenticate a connection to a network of the electronic conference system, from the network management equipment to a common key code device;    rewriting a network setting of a user's terminal to a setting corresponding to the network of the electronic conference system, by reading the common key code from the common key code device installed into the user's terminal; and    connecting the user's terminal to the network of the electronic conference system based on the rewritten network setting of the user's terminal.
